Adaptive Toolpath Problem

[Anonymous]

I am trying to use Adaptive Clearing feature on this part (please check the attached file). I want to use 20 mm flat end mill, 14.5 mm optimal load (stepover), 10 mm axial depth of cut, 0.25 mm radial stock to leave and 0.1 mm axial stock to leave. However Fusion keeps giving error of "Empty toolpath). I couldn't find the reason of this error. Any help will be appreciated. Thanks in advance.

Lower your Minimum Ramp Diameter to 5mm, it's on the last tab of the toolpath settings.

Thank you for your quick response. That solved the problem. I have one more problem. I would like to drill a hole to the middle of the part but my model doesn't have a valid hole for this operation. How can I define a hole manually?

[seth.madore]

Project your profile of the hole and keyway, manually sketch in a circle approximate to it's location.

Use "Selected Points" to drive your drilling cycle.

However, I'd STRONGLY encourage you to re-draw that feature properly, especially if you plan on machining this part with any degree of accuracy. An imported sketch is often error prone, as you can see from your resulting file. 

Looking at the part, it does appear that the origin is set to center of the bore, so it gives us a clue as to where to start..

The real issue with this part is this:  we will produce it from a sample part provided by our customer and the part has a difficult splines to measure accurately even with using a Faro Arm. Therefore we sent the part for scanning. The resulting file from the scan is a DXF file which contains thousands of points instead of splines or arcs. We extruded that DXF file and built a solid model. When you look inside the pocket you will see what I mean. I would like to know that is it safe to machine this part with using this model or we should look for another method for measuring the part and creating a better solid model. When I create 2D contours for finishing, it doesn't look like toolpath follows the contour flawlessly. But this can be a problem about the visual representation  not the toolpath itself.

Hi ,

i had a look at your part and see the problem with multiple segments. I saw this on linedin and thought if you have a rep in the area maybe they could get you a better model from a points cloud?
